Project Overview
Polkadot is a cross-chain protocol designed to connect and secure different blockchains. It provides interconnectivity and interoperability between them, enabling independent chains to securely exchange messages and perform transactions without relying on a trusted third-party. This allows for cross-chain transfers of data or assets between different blockchains, as well as the development of cross-chain DApps (decentralized applications) using the Polkadot Network. The Web3 Foundation is responsible for building Polkadot.
21Shares Polkadot ETF's Q2 "Staking Yield" Comes at a Cost: $4.52 in Losses for Every $1 in Rewards Paid
Odaily News - The latest disclosure from 21Shares' Polkadot ETF (TDOT) shows that in Q2 2026, the fund sold DOT tokens to pay staking rewards, incurring approximately $4.52 in realized losses for every $1 in distributions generated.According to regulatory filings, TDOT sold 98,505 DOT in Q2, generating approximately $107,500 in cash to pay staking rewards to shareholders. However, due to the sharp decline in DOT's price, these sales confirmed approximately $485,600 in losses.Data shows that DOT fell approximately 34% in Q2 2026, with a cumulative decline of 76% over the 12 months ending June 30. Since TDOT shareholders receive USD-denominated distributions rather than DOT staking rewards directly, the fund must sell DOT to convert to cash payments, thereby locking in losses in a low-price environment. In Q2, TDOT paid shareholders approximately $0.14698 per share in distributions, but the fund's share price fell from $14.95 to $9.86 during the same period, a decline of roughly 34%. Staking yields did not offset the losses from the decline in asset prices. (Protos)
Kalshi applies to launch perpetual futures for 12 tokens including Ethereum, XRP, Solana, and Dogecoin
Prediction market platform Kalshi has submitted a self-certification application to launch derivatives linked to Ethereum, XRP, Solana, Dogecoin, Stellar, Chainlink, Bitcoin Cash, Litecoin, Sui, Shiba Inu, Polkadot, and Hedera. This follows the CFTC's approval of Bitcoin perpetual futures last Friday. The CFTC stated that perpetual futures products that US companies intend to list, other than Bitcoin, will be reviewed on a case-by-case basis, and noted that the design of such derivatives may not be suitable for all asset classes. Therefore, this batch of products submitted by Kalshi has not yet been approved.
Hyperbridge: Losses from the vulnerability increased to approximately $2.5 million; some funds have been traced to Binance.
According to an official disclosure by Hyperbridge, the losses from the Token Gateway vulnerability incident on April 13 have been revised upward from an initial estimate of $237,000 to approximately $2.5 million. The increase stems primarily from losses incurred in incentive pools on Ethereum, Base, BNB Chain, and Arbitrum. The attacker extracted roughly 245 ETH from related contracts, then bypassed the MMR proof verification mechanism by forging cross-chain messages, minting 1 billion bridged DOT tokens and dumping them onto illiquid markets. Currently, some of the stolen funds have been traced on-chain to Binance. Hyperbridge is collaborating with Binance’s compliance team and law enforcement agencies to investigate the incident. Polkadot-native DOT and products such as Intent Gateway remain unaffected. The Token Gateway and bridged DOT contracts on the four affected EVM chains remain suspended. An external audit of the patched MMR verification logic is underway, and bridging functionality will be restored upon completion of the audit.
Polkadot Responds to Hyperbridge Vulnerability: Polkadot and Native DOT Unaffected
Polkadot’s official response to the security vulnerability discovered in Hyperbridge’s Ethereum gateway contract: Hyperbridge services have been temporarily suspended to investigate the issue. This vulnerability affects only DOT tokens bridged to Ethereum via Hyperbridge and does not impact DOT tokens within the Polkadot ecosystem or DOT transferred via other cross-chain bridges. The Polkadot mainnet, parachains, and native DOT remain secure and unaffected.

Hyperbridge Contract Hit by MMR Proof Replay Vulnerability, Suffering ~$242,000 in Losses
According to BlockSec Phalcon, the HandlerV1 contract managed by Hyperbridge on the Ethereum network was found to contain a Merkle Mountain Range (MMR) proof replay vulnerability, resulting in approximately $242,000 in losses. The vulnerability stems from the lack of binding between proofs and requests, enabling attackers to replay historical valid proofs alongside newly forged requests to perform malicious actions—such as altering administrator privileges. In the specific incident, the attacker changed the Polkadot (DOT) token administrator and then exploited those privileges to mint additional DOT tokens for profit. Observed attack transactions include: changing the DOT token administrator and minting new tokens (losses of ~$237,400), changing the ARGN token administrator and minting new tokens (losses of ~$3,800), and host withdrawal operations. The vulnerability was discovered by PhalconSecurity and analyzed via PhalconExplorer. Previously, the Hyperbridge gateway contract was attacked, leading to the unauthorized minting and subsequent dumping of 1 billion DOT tokens on Ethereum.

Polkadot Community Proposes DAO Strategy Mandate: Shifting from TVL to User Acquisition and Launching Collateralized Stable Asset dotStables
the Polkadot community recently submitted a proposal on the SubSquare platform titled "DOT DAO Strategy Mandate," advocating for a shift in the DAO's strategic focus from ecosystem expansion and total value locked (TVL) growth to end-user acquisition and real-world use cases, and planning to build a user-facing Polkadot Product Platform.Another core component of the proposal is the launch of a permissionless DOT-collateralized stable asset called dotStables, with priority support for dotUSD. The asset adopts a collateralization model similar to Liquity, aiming to ultimately convert stablecoin demand into demand for DOT. In terms of platform design, it will be compatible with existing parachain infrastructure and emphasize a freemium model, mobile-first approach, self-custody, privacy protection, and login-free user experience. Currently, the proposal is still in the governance preparation stage.
Polkadot's native stablecoin dotUSD officially launches, managed by on-chain governance mechanisms
Odaily — Polkadot has officially announced that the stablecoin dotUSD has officially launched on the Polkadot network. The stablecoin has no single issuing company or controlling entity; instead, it is managed by the DOT DAO through the OpenGov on-chain governance mechanism. Polkadot stated that dotUSD aims to become a native stablecoin governed by the network itself, thereby reducing reliance on centralized issuing institutions.
Polkadot Plans to Launch Native Stablecoin dotUSD with $5 Million in Initial Funding
Odaily News: The Polkadot community has initiated OpenGov Proposal No. 1944, aiming to create a native decentralized stablecoin called dotUSD and establish it as the primary stable value asset within the Polkadot ecosystem. The proposal is currently undergoing governance voting. According to the proposal, dotUSD will adopt an over-collateralization mechanism, allowing users to mint dotUSD by locking DOT in the future. The system will also include a stability pool, liquidation mechanism, and redemption mechanism to maintain its peg to the US dollar. The proposal plans to use funds from the Polkadot treasury to provide initial liquidity for the DOT/dotUSD liquidity pool, with $2.5 million in USDT used to mint dotUSD and an additional $2.5 million worth of DOT allocated to the liquidity pool, bringing the total initial funding to $5 million. dotUSD is planned to launch in phases, with the first phase using USDT as reserve backing for minting, and the second phase introducing a full DOT collateral vault, oracle, stability pool, liquidation, and redemption mechanisms.
Grayscale withdraws three ETF registration applications for ADA, HBAR, and DOT in succession, without disclosing specific reasons
Odaily News – Grayscale withdrew three ETF registration applications for Cardano (ADA), Hedera (HBAR), and Polkadot (DOT) in succession on August 7, with the three withdrawal filings submitted approximately 190 seconds apart.All three withdrawal filings indicate that Grayscale no longer plans to proceed with the issuance of shares for the related ETFs.
